I got my Xaos21-98sq.ft. a few months ago and I love it! I jumped a 9cell with similar size before. The difference is huge! The flare is amazing, the openings are very soft.
Important: Don't buy a Canopy in this performance range before you're ready. I have had 300 jumps on a 95sq.ft. 9cell before, but this Xaos is just another league! The speed is amazing. When you release the brakes you can feel the acceleration and my first thought was: How am I going to land this monster?
Openings are great if the pack job was good. This is not a Spectre! If you pack shitty, that's the way the canopy will open. So be careful. I didn't have a twist so far and believe me, I don't want to have one!
For my taste, front riser pressure in full flight is a bit high. But you can steer just by shifting weight in the harness. Overall, the best canopy I've ever jumped. In the crossbraced-range I jumped the Neos and the Velocity as well.
blue sky!
